I have used Open Office quite a bit, and it’s more than slightly behind MS Office. I will agree that it’s absolutely free, and you can do quite a bit with it.

OpenOffice / LibreOffice are fine as long as you never attempt to use them for business. If you do, expect trouble. I tried several times, and it never worked right. I have MS Office 2003 on this computer, and MS Office 2010 elsewhere, and they are parsecs ahead of OpenOffice, even with their stupid ribbons.
